[Curved Ramp]

Hello @ericjhbergI thought I responded to your comments earlier but I can't seem to find what I posted.

1. Is there any way to make the horizontal curvature more regular? I know this is using nurbs, so the answer may very well be no, but we often are trying to design ramps on a radius which is difficult to do accurately with nurbs or bezier curves.

 

- In order to make this path based (allow it to have control geometry that was editable with the reshape tool), I found the easiest way to accomplish it was using a Bezier curve. To write it using a poly with arc vertices would be a very different script. How would you draw the 2D profile of a ramp?

 

2. The cross slope profile created by the loft surface can create some pretty extreme cross slopes. Is there a way to better control this?

 

- I built the ramp by dividing each edge length equally and stepping it that way, I didn't know how to best calculate slopes for ramps. for stairs it is a matter of finding a tangent to the curve but with a ramp I imagine you want you slope to be shallower going around curves and steeper on straightaways. Any pointers on how you would model this would be greatly appreciated. Maybe even starting with how NOT to do it is helpful.

I'm sorry but this file uses capabilities that are not available in Vectorworks 2016, namely importing a Python library. This Marionette object and the other Weather Analysis MOs use an external Python library that gives you latitude and longitude based on an address/location.
